has been removed from the -mm tree. Its filename was
gx1fb-properly-alloc-cmap-and-plug-cmap-leak.patch
This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
Subject: gx1fb: properly alloc cmap and plug cmap leak
From: Andres Salomon <dilinger@xxxxxxxxxx>
We weren't properly allocating the cmap for depths greater than 8bpp,
which caused pain for things like DirectFB. Also, we never freed the cmap
memory upon module unload..
